Descrição técnica

Open WebUI 0.11.0 before 0.11.4 compiles user-chosen grep patterns for its knowledge and chat file search tools with a regex engine that expands nested counted repetition unbounded at compile time and caches the result. Authenticated users can have the model call grep_knowledge_files with short nested-repetition patterns, blocking the event loop and exhausting worker memory.

———Allocation of Resources Without Limits or Throttling vulnerability in elixir-grpc grpc_server allows unauthenticated attackers to exhaust memory and crash the node via an oversized client-streaming or bidirectional-streaming request body. The streaming read clause of 'Elixir.GRPC.Server.Adapters.Cowboy.Handler':info/3 (grpc_server/lib/grpc/server/adapters/cowboy/handler.ex) never checks the configured max_body_size. Only the unary read path enforces that cap. 'Elixir.GRPC.Server.Adapters.Cowboy':reading_stream/1 (grpc_server/lib/grpc/server/adapters/cowboy.ex) appends every received chunk to its buffer until a complete length-prefixed message arrives. A client can declare a very large message and send it across many small HTTP/2 DATA frames, and the server buffers all of it. This issue affects grpc_server: from 1.0.0 before 1.0.6.6h CVE-2026-591715.9 MÉD

———JSON-java is a reference implementation of a JSON package in Java. From version 20150729 through 20260522, JSONTokener.nextSimpleValue can accumulate unbounded numeric tokens before JSONObject.stringToNumber passes them to BigInteger or BigDecimal conversion without a length limit. An application that parses attacker-controlled JSON or XML through JSONObject, JSONArray, or XML.toJSONObject can spend super-linear CPU time converting a sufficiently long numeric literal, blocking request-handling threads and causing denial of service. Strict mode and keep-strings settings in JSONParserConfiguration do not prevent the affected conversion path. Version 20260719 limits numeric conversion length.6h CVE-2026-1239976.5 MÉD

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated denial-of-service vulnerability in the UPnP/DLNA AVTransport SOAP service that allows LAN-adjacent attackers to freeze the entire television software layer by sending a crafted SetAVTransportURI request on TCP port 38400. Attackers can exploit this flaw without credentials to render the device completely unresponsive to remote control or front-panel input, requiring a physical power cycle to restore functionality.8h CVE-2026-1233567.5 ALT

——0GROBID is machine learning software for extracting information from scholarly documents. Prior to 0.9.1, the unauthenticated /api/modelTraining endpoint calls GrobidRestProcessTraining.trainModel in GrobidRestProcessTraining.java, where each request creates Executors.newFixedThreadPool(1), submits a training task, and leaves the executor running. Repeated requests permanently retain JVM worker threads and can exhaust process or operating-system thread capacity, degrading or stopping request processing. This issue is fixed in version 0.9.1.8h CVE-2026-1237484.3 MÉD

——0A security flaw has been discovered in chenyme grok2api up to 3.1.6. Affected by this vulnerability is the function proxyVoiceWebSocket of the file backend/internal/transport/http/inference/voice_ws_handler.go of the component WebSocket Proxy. The manipulation results in resource consumption. The attack may be launched remotely. Upgrading to version 3.1.7 addresses this issue. The patch is identified as 7ad0f791f0a9eb5a0ddfe38ac4dfcef01e19a6d4. It is suggested to upgrade the affected component.9h CVE-2026-1026507.5 ALT

——0Nuxt Content is the file-based CMS for Nuxt applications, powered by Markdown and Vue components. From 3.0.0 until 3.15.2, the unauthenticated POST /__nuxt_content/:collection/query endpoint accepts an attacker-controlled sql field in src/runtime/api/query.post.ts and permits expensive SQLite expressions. Version 3.0.0 performed no query validation; in affected releases using assertSafeQuery in src/runtime/internal/security.ts, the reported validation gap rejects a short list of SQL command keywords in WHERE clauses but permits function calls including randomblob(), zeroblob(), hex(), and length(). The query reaches the synchronous better-sqlite3 sink in src/runtime/internal/database.server.ts, allowing a single remote request to consume substantial CPU and memory while blocking the Node.js event loop and all concurrent request handling. Fully static prerendered deployments that do not expose the server endpoint are not affected. This issue is fixed in version 3.15.2.9h
